Hypothesis: If i add the egg to vinegar then the shell will dissolve within 24 hours
nadezda [96]

Answer :

Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell.  The calcium carbonate shell gets dissolve.

Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.

When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.

Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.

Difference between incomplete and complete ventilation? any 4​
Temka [501]

Answer:

Due to exchange of gases i.e. normal and abnormal.

Explanation:

The main difference between incomplete and complete ventilation is the occurrence of normal and abnormal exchange of gases. The mechanism in which the exchange of gas happens completely without any difficulty is called complete ventilation. It is the process in which the required amount of oxygen is inhaled or inspired and appropriate amount of carbon dioxide is exhaled out of the body while on the other hand, incomplete ventilation is a mechanism in which exchange of gases is not normal.
